"Ron was on time, made great options with good reasoning behind layout of installing Mini Split Air Conditioning Units. Same day estimate sent via email with breakdown of cost. Installed right away and done in one day. The crew was very professional and easy to work with. I would recommend Cawiamca to anybody in need of AC installation in fact I already did to my niece."

"I feel fortunate to have been able to meet Chris and have him fix my HVAC issues. He was prompt, excellent at communicating, and also is a great listener. The cost of my service wasn't low due to what was needed but it was more affordable than other quotes I'd recieved; some of the others who had spoken to me on the phone were indicating rates that were 50% higher than what Chris charged for the same exact product! I'll gladly hire him for future work. I've already given his number to others with HVAC needs."

"We hired Bill Aitken Heating to repair our gas furnace, we had an accumulation of water in the furnace pan. I called Aitkens Heating and received a call back immediately. They were here promptly at the time scheduled for repair. Mr. Aitkens had my furnace repaired within a half hour. He arrived with his helper and I could not be more satisfied with the work these gentlemen did. Bill took the time to explain in detail what he did for the repair. Bill Aitken is our GO TO man for any of our heating and air condition maintenance. I would like to add he was very reasonable. My husband was not available to over see this project so I handled the whole project from start to finish. BILL AITKEM HEATING LLC. comes very highly recommended by the Perkins family."

"The central air conditioning stopped at 7pm with 90 degree weather. Lloyd sent an email immediately. He came that evening and the following morning to fix the problem. He was very polite and answered all my questions. The total fix was $256 which matched what other companies have charged in the past for the same issue. I would hire him again."

FAQs for air conditioning projects in East Lyme, CT

Most professional HVAC technicians require two to three hours to complete an expansion valve replacement. The timeframe depends on your unit's accessibility and whether additional repairs are needed. The process involves recovering refrigerant, removing the old valve, installing the new component, and recharging the system. Scheduling during less busy seasons may result in more convenient appointment times.

Operating your air conditioner with a malfunctioning expansion valve isn't advisable. Continuing to run the system could potentially damage other components, particularly your compressor, which is significantly more expensive to replace. If you notice performance issues like inconsistent cooling or unusual noises, it's best to have your system inspected before continuing regular use.

Expansion valves don't have a standard replacement schedule, as their longevity depends on system usage, maintenance frequency, and environmental factors. Regular professional maintenance helps identify potential valve issues before they cause system failure. Having your HVAC system serviced annually allows technicians to monitor component condition and recommend preventative replacements when necessary.

Refrigerant leaks require prompt professional attention. If your expansion valve is leaking, you'll likely notice reduced cooling performance and possibly hear hissing sounds near the unit. Addressing leaks quickly prevents further system inefficiency and avoids the environmental impact of released refrigerant. Your HVAC technician will need to repair the leak and recharge the system with the proper refrigerant type and amount.

Because many AC issues present similar symptoms, professional diagnosis is recommended. Problems like inadequate cooling, inconsistent temperatures, or strange noises could indicate expansion valve issues, but might also stem from refrigerant leaks, electrical problems, or airflow restrictions. A qualified HVAC technician has the tools and expertise to accurately identify the root cause and recommend appropriate repairs.
